Installation and startup Basic circuitry and connections for the measuring chain When the applied torque changes, the reaction torque sensor produces an electric charge. The charge signal is con- verted into a proportional output voltage by the charge amplifier, which can then be measured and recorded by an electronic evaluation system.

Kistler special cables and Kistler charge amplifiers are used. Calibrated measuring range Measuring range or part of the measuring range for which the sensor has been calibrated. Because of the high linearity of quartz crystal sensors, the sensitivity of a measuring range can usually also be used for smaller measuring ranges.

Reaction torque sensors Type 9329A, 9339A, 9349A, 9369A, 9389A 10.2 Measurement uncertainty Systematic errors, accuracy Accuracy is the extent of the conformity between a measured value and a true value of the measurand. In a piezoelectric measuring chain it is determined by many systematic errors, e.g.
Errors due to zero drift caused by in- fluence quantities changing with time, such as the temperature, are thus basically excluded. With Kistler piezoelectric measuring chains, a typical repeatability within 0,1 % FSO can be assumed. 10.3 Linearity...

Reaction torque sensors Type 9329A, 9339A, 9349A, 9369A, 9389A thus ideal for measuring measurands which change rapidly over time. Their dynamic behavior is thereby largely determined by the surrounding structure. Therefore the frequency response of the entire measuring arrangement must be investigated for the largest possible, useful measuring range.

Annex Temperature gradient error (dynamic error) A temporary change in the output signal is denoted as tempera- ture gradient error, when the temperature of the environment or surrounding medium changes with a certain rate. In this case, the sensor is not in thermal equilibrium with the environment. The temperature gradient error is primarily determined by the installation conditions and the application, and cannot be gen- erally specified.
